When you are driving and you spot a particularly attractive wench near a roundabout, you continue going around the roundabout ignoring any of the exits and concentrating firmly on the attractive pedestrian. The quality of the goods on show can be judged by the number of orbits completed.

You should have seen the girl standing by the roundabout this morning, she was a triple orbiter make no mistake.

I got caught orbiting last night, she knew exactly what I was doing by the 12th lap.
